I have a Tube injection mold from A.I. Say for instance, I want to do an orange inside, and green pumpkin outside color. Can I just inject the orange? Keep them on the rods and just dip in the green pumpkin? do I need the 2nd color to be hotter than normal? I tried this once before about a year ago and the outer color never stuck to the injected color. Any help would be appreciated.
